CASTING APPARATUS.

SPECIFICATION formingparhof Letters Patent No. 215,713, dated December 9, 1902.

To all whom it may concern:

Be it known that I, HERBERT G. UNDER- WOOD, a citizen of the United States, residing in the city, county, and State of New York, have invented a certain new and useful Casting Apparatus, of which the following is a specification, reference being bad to the ac- This invention is especially designed for use, in connection with apparatus in which the molten metal or other material is forced of supply through asuitable exit port or noz :ale; and it has for its object the production f mechanical means which are simple and *ractical in construction, durable and strong in use, present the mold with great rapidity to receive the material to be cast, hold the mold and its component sections or parts The invention consists in the matters herepended claims.

The accompanying drawings illustrate a casting apparatus which I have designed and chosen for explanation of my invention, and in the drawings Figure 1 is a side elevation of the apparatus. Fig. 2 is a front elevation of the same. Fig. 3 is a view similar to Fig. 1 of a slightlylnodified form of apparatus. Fig. 4 is a front elevation of the means shown in Fig. 3; and Fig. 5 is a detail View, partly in section, of the apparatus seen in Figs. 3 and 4.

The melting-pot or other source of supply shown as having a top or cover B, which supports a cylinder or chamber 0, Fig. 5, within the part A and the molten material therein. Said cylinder or chamber 0 is illustrated as relatively fixed to the melting-pot or source of supply A and as provided with ports 0 c and with a plunger D, operated by means here shown as a lever L. The outlet-port c of the cylinder or chamber 0 communicates with an exit port or nozzle E, which is preferably arranged substantially upright and provided with a tapering end face 6, Fig. 5.

The parts thus far described comprise the means for supplying the material to be cast .ways.

and are each of any suitable ordesirable form, size, and construction.

The remaining parts of my apparatus form the mold supporting and manipulating means and may be constructed in many different In the illustrated embodiment of my invention, F is a supporting member, and G is a mold. As shown, the member F is pivoted to the top or cover B and is provided with a port or orifice ffor registering with the exit port ornozzle E, and with means, as the handle F for rocking said member F on its pivot relatively to the exit-port E' and alternately presenting the port or orificef to the exit port or nozzle E and removing the same from said part E.- The handle F may, however, be dispensed with and any other part fixed to the supporting member F, as the upper end of the standard rising from said supporting member may be used as a handle. The face of the supporting member F opposed to the exit port or nozzle E is generally provided with a tapering surface F for engaging the end face e of the exit port or 7 nozzle E, and the opposite face of the member F is provided with suitable engaging means, as dowel-pins f.

The mold G is. composed of any desirable number of sections or parts, here illustrated as two, is mounted directly on the supporting member F, and its section or part adjacent to the supporting member F is shown as detachably engaged with the meansf. Said mold G is preferably provided with an ingate g, opening from its face opposed to the supporting member F and normally registered with the port or orificef, and during the entrance of the material is firmly pressed rectilinearly or in a right line toward the opposo ing face of the member F and the exit-port E by suitable means, which is here illustrated as supported by the standard rising from the member F and a second supporting member secured to said standard and as consisting of a clamping member and toggle-levers between the second supporting member and the clamping member.

In Figs. 1 and 2, the standard rising from the supporting member F is shown as a pair mo of separatedsubstantially parallel arms H H, having threaded ends h, and the secand supporting member is shown as a crosshead I, provided with a fixed stop 1; and having its opposite ends adjustable lengthwise of the arms H H and engaged by suitable means, as nuts 77., provided on the threaded ends of the arms H H for securing the supporting member or cross-head I in its adj usted position relatively to the supporting member F. As illustrated in said Figs. 1 and 2, the clamping member, which is represented by J, is movable rectilinearly or in a right line toward and away from the opposing faces of the supporting members F I and relatively to the handle F ,and the standard rising from the supporting member F is guided at its ends on the arms H H and is provided with means, as doWel-pinsj, for detachably engaging the contiguous section of the mold G and moving the same as a whole toward and away from the rem-aiming portion of the mold in order to permit the ready removal of the cast articles from the mold. The toggle-levers K K, Figs. 1 and 2, are of any desirable form, size, and construction, are operated by any suitable means, as a hand-lever N, fixed to one of said levers, are interposed between the second supporting member I and the clamping member J, and when in their operative position the pivots 1, connecting the ends of the toggle-levers pivoted together, are alined with the pivots for connecting the other ends of the toggle levers to said supporting and clamping members I J in order that the clamping member J may be positively locked in its position assumed during the entrance of the material to be cast. As the toggle-levers K K are operated, the pivots 1 move into and out of their locking position, and as said toggle-levers assome their operative position the movement thereof is limited by the stop 1', which encounters the contiguous toggle-levers.

In the use of the apparatus shown in Figs. 1 and 2 the two sections or parts of the mold G are deta'chably engaged, respectively, with the supporting and clamping members F J. The hand-lever N operates the levers K K and the clamping member J to move the section of the mold engaged with the niemberJ rectilinearly toward the opposing section of the mold. The supporting member F is swung on its pivot for presenting the port fto the exit port or nozzle E to permit the entrance to the mold of the material to be cast, and during the entrance of said material the clamping member J firmly presses the mold as a whole toward the contiguous face of the supporting member F and the'exit port or nozzle E, and the pivots I lock said clamping member J in its operative position. If the desired operation of the clamping member J and the levers K K does not take place, the second supporting member I may be adjusted vertically. After the formation of the cast article in the mold the supporting member F and the hand-lever N are respectively operated to withdraw the port f from the exit port or nozzle E and to separate the sections of the mold to permit the removal of said cast article. These several operations can obviously be completed with minimum ease and maximum rapidity.

The construction of my apparatus seen in Figs. 3, 4, and 5 is substantially identical with that seen in Figs. 1 and 2, with the exception of the standard provided on the supporting member for the mold, the clamping member, one of the toggle-levers, and the means for supporting and actuating said'toggle-lever. In Figs. 3 to 5, inclusive, the standard H consists of a single upright or bracket. The clamping member J is guided on said standard at one end only. The toggle-lever K which operates the toggle-lever connected to the clamping member J, is mounted on a supporting member k projecting laterally from the standard H and is provided with a rigid arm connected to a link K which is pivoted to the top or cover for the melting-pot and serves to move the clamping member J to and from its operative position when the supporting member from the mold is moved to and from its position assumed during the entrance within the mold of the material to be cast.

The construction and operation of my casting apparatus will now be readily understood upon reference to the foregoing description and the accompanying drawings, and it'w'ill be obvious that more or less change may be made in the construction and arrangement of the parts thereof without departing from the spirit of my invention.
